Not long ago, the country (in the USSR since 1987) launched the production of CBPB. What are the uses of cement bonded particle boards in modern construction and what do they represent?
DSP is a sheet composite material, for the manufacture of which medium and thin wood chips (24%) are used, Portland cement M500 (65%), special chemical additives (2.5%) to reduce negative impact wood extracts for cement, and water (8.5%) (Image 1). The slabs are produced by pressing at a temperature of 900°C for 8 hours. After this, the products are kept at natural conditions for 2 weeks.
The most famous domestic manufacturer is the Tamak plant in Tambov. Plates are also produced by TsSP-Svir (St. Petersburg), Kostroma TsSP Plant, Omsk Stropan, Tyumen Sibzhilstroy and Plant building structures, located in Sterlitamak.
Russian products meet the requirements of GOST 26816-86. It is divided into 2 brands: TsSP-1, TsSP-2. The latter grade of sheets is subject to less stringent requirements than TsSP-1.
Cement particle boards have:
But cement particle boards, specifications which are generally good, also have a number of disadvantages:
The versatility of the boards allows them to be used to solve various construction problems.
First of all, these are external works: construction of frame buildings, finishing of facades of residential buildings, warehouses and agricultural premises, use as a basis for soft roofing, fencing of balconies and loggias, use as permanent formwork for the foundation.
Facade cladding (Image 4) is carried out by attaching cement-bonded sheets using nails, self-tapping screws, metal brackets or screws to a frame made of wooden beams or metal profile. Optimal step sheathing is 60 cm, it is preferable to attach the beams vertically; for small areas they can be used horizontal installation. Gaps of 4-5 mm are left between the sheets, which prevent their deformation when the air temperature changes. The gaps are filled with elastic mastic or a sealing gasket, which is covered from the outside with purchased or made from chipboard scraps. Depending on the purpose of the building, the space between the wall and the slabs can be left empty, or it can be filled with modern insulation; this is very important for residential buildings. After fastening, the sheets are primed and applied decorative plaster or just paint it.
When making a base for a soft roof, you should pay attention Special attention for waterproofing joints. Technologically, the process of manufacturing a base from DSP is similar to working with wood materials.
For fencing balconies and loggias, using cement-bonded particle boards is much more expedient than those used asbestos cement sheets, because instead of fragile material, a strong and durable fence is built.
DSP formwork (Image 5) is increasingly used in the construction of low-rise buildings. It provides:
Due to the complete absence of the release of any harmful gases and vapors during operation, cement particle boards are recommended for interior decoration premises (Image 6): they are used to level the walls (either attached to a frame made of the most rigid reinforced profile, or a special solution or mastic), form internal partitions, especially in conditions of high humidity (to increase service life, such a partition should be treated with a water-repellent agent and painted with waterproof paint).
DSP boards are also used for flooring (Image 7), and their use is preferable to the use of chipboard (chipboard) or oriented strand board (OSB). Typically, the laying of DSP for flooring is carried out on logs having a cross-section of 50x80 mm, in increments of 600 mm.
With the help of DSP you can:
The thickness of the DSP is:
Cement particle boards can be safely recommended for performing the above work. But you need to use the products domestic manufacturer, and do not purchase Chinese DSPs. Using the products of hardworking Asians can lead to swelling of the slabs, their chipping, the sheets themselves may be crooked and the surface uneven.
The construction industry is one of the most actively developing today. Periodically on the market building materials new technological solutions are emerging. One of these innovations is DSP boards, the sizes and prices of which have greatly pleased both specialists in this field and ordinary consumers. Today, together with HouseChief experts, we will try to figure out what is unique about this building material, what are its positive traits, and does it have any disadvantages?

The uniqueness of the sheet building material, which received the short name CSP (cement particle board), lies in the fact that it managed to combine seemingly incompatible components - Portland cement and crushed wood shavings. This became possible due to the introduction of special hydration additives that neutralize the harmful effects of the components included in the slabs on each other. Modern manufacturers learned to make slabs without the use of phenol and formaldehyde, which are harmful to human health.
Technically, the process of making plates is as follows:
The ideal smooth surface allows you to evenly or wall. If you cover a house with panels and paint them one of pastel colors, then you get a classic facade in , where main role Decorative strips covering the joining seams between the panels will play a role.
Water-repellent properties have made products based on chips and indispensable for finishing wet areas.

DSPs have proven themselves to be excellent in the construction of frame-type houses. There are two options - purchasing a ready-made house kit based on DSP or independently erecting walls between which the mineral insulation. The slabs are fixed using wooden or metal sheathing, while sewing up the frame around the perimeter, and after that the House is cut out using frame technology using DSP

Wood processing technologies in Lately are gaining momentum. That is why today boards based on shavings, sawdust, and laminated materials, which are used in furniture production, are used everywhere.
CSP - cement particle board, which has a sufficient level of strength. This allows them to be used in construction matters frame houses, where they are used on floors and walls. If somewhere such boards can be replaced with chipboard, OSB and others, then DSP will be especially relevant where humidity is high, for example, in a bathroom, toilet, furnace room. For the same reason, they can even be used for finishing facades, as well as as a roofing base before installation soft roof.
Cement particle boards
Speaking about the features, it is worth analyzing the structure of this material. The main thing that gives the slab grey colour, is cement. According to GOST, its mass fraction must be at least 65%. At the production stage, gypsum is added to it, as well as additives that increase plasticity.
The second component is considered to be shavings. Its mass fraction is at least 24 percent. The remainder includes water, as well as binding additives. Water, after reacting with cement and additives, evaporates, leaving space with air. This results in the slab becoming lighter and warmer.
Like any types of building materials, CBPBs have a number of varieties. Their subtleties concern the production moment, since these plates look different, are used in different industries, have unique features.
The first option is fiberboard. The base used here is not wood shavings, but fibers, which makes the base viscous and especially tensile. To achieve additional strength, it is used at the production stage liquid glass and calcium chloride.
Thanks to their resistance to damage, the products are not only able to withstand heavy loads, but also resist the effects of sound. That is why fiberboard is often used as sound insulation in studios, shopping centers, bars, and discos. Despite these properties, fiberboard is easy to process yourself. To do this you do not need to have any special tool. It is easy to process even at home.
1. . This is the second version of the variety. Here sawdust is used as a wood binder. Rice straw and reeds are used as the production basis. Among all the raw materials used for production, wood chips provide the highest strength.
The performance characteristics here are lower than those of the above option, but the cost of such a product is also cheaper. As for the total weight, the sheets are heavier, but suitable for walls. That is why they are used to decorate low-rise frame houses of private construction.
Production of CBPB boards
2. Xylolite. This is the third variety. The strength of such products is so high that they can be used for both floors and walls. Lumber, namely wood chips, is used as the basis for production. On sale you can find not only the colors of the standard segment, but also various shades, which turns out to be quite beneficial in terms of finishing. Sometimes they are even left without additional cladding, because the background general interior they look interesting and expensive.
Characteristics of CBPB boards important at the selection stage:
The technological feature of production allows us to produce slabs of different thicknesses on the market. Basically, they are fixed values from 0.5 centimeters to 4 cm, inclusive. The width may also vary. It is fixed at 120 and 125 cm, respectively.
Dimensions of CBPB boards
As for the length, this value is fixed at 270 and 320 cm, respectively. State standard production assumes deviations in the thickness, width and length of the material up to one and a half mm, inclusive.
Regarding the scope of application, it is necessary to highlight the sphere of private and capital construction. A private developer can use this material everywhere, starting with finishing floor surfaces and finishing with wall decoration. DSP slabs for flooring have found their application.
They are able to withstand heavy loads and are easily processed using special paints. They do not disturb the interior to some extent; on the contrary, they give it a finished look. The main thing is to perform the installation correctly, because if there is a violation technological process there is a possibility of losing the aesthetic appearance, as well as reducing the service life of the slab.
As for other areas of application, they are used for arranging the foundation. This is the so-called permanent formwork, with which the frame is made. The slabs are cheap, so it is convenient to use them here and leave them for later use.
They will be easy to finish on the outside, which will not disrupt any aesthetics in the long run. appearance Houses. Frame technology also assumes application of DSP slabs as a basis for future walls and ceilings. I also use DSP boards for the partitions to construct the frame.
DSP is used in the construction of frame houses
Today they are used in frame-type houses, and where they are used to hem ceilings, and they can also be used for roofing structures followed by finishing soft material. Such slabs are hemmed reverse side stairs, sewing up communication niches, making blind areas and paths in the garden, and installing subfloors.
The most important thing to know DSP dimensions slabs. For the ceiling, for example, it is most suitable thin material, since it will fulfill its task of arranging the base even with the smallest thickness. Otherwise, the floor needs a thicker base, since its resistance to loads should be maximum. The same can be applied to formwork.
Installation of DSP slabs can be made by hand. It’s not difficult, the main thing is to follow the basic rules of work. As for the basic rules, we suggest considering installation using the example of arranging the facade of a private house. Here you need to follow the following steps:
1. The foundation needs to be established. These are a kind of bars measuring 50 by 50 mm, which must be fixed to load-bearing wall. If we have a frame house in front of us, then we can use the existing frame without additional modification.
Since the plate itself weighs a lot, it is not recommended to use a smaller cross-section, unless you can replace it with metal, 50 by 20 mm. The step between two adjacent beams should be no more than 60 cm. Vertical sheathing is performed with the specified step.
2. The insulation is being laid. For this reason, we previously chose a cross-sectional area of 50 by 50 mm. This is convenient for laying insulation with an overlap of 2 and 2 cm, respectively. The overlap is done in order to remove cold bridges at the junction of two plates.
Depending on the original base, the insulation is nailed either with special dowels or fixed to the wooden profile by further installing a wind protection membrane. The membrane is nailed to the tree using a stapler. One cm of space left between the insulation and the DSP board is a ventilation gap. It must be left during installation.
3. Installation of sheets. It is advisable to lay the first sheet perfectly level in order to limit the overall horizon for subsequent installation. The sheets are screwed using a regular wood or metal screw, depending on the base.
Before screwing the sheet, level it, fix it and make markings for further installation. Manufacturers recommend drilling holes for screws. To do this, use a drill of a smaller diameter. If you are not going to drill, then buy self-tapping screws with a drill.
Fasteners must be galvanized or pre-treated with special compounds. It is impossible for two adjacent slabs to fit perfectly against each other. It is important to leave a ventilation gap, which can be up to 0.5 centimeters inclusive.
4. Don’t worry if parts of such a slab break off somewhere. In the future, you can always cover the walls with another material, but even small chips will not harm the overall integrity of the surface. The easiest way to further finish is to paint the surface.
Frame house sheathed DSP
There are special paints for CBPB, which will give your home a sophisticated look. Paints are produced on the basis of acrylic or silicone, which makes them moisture resistant and allows them to maintain their saturation at critically low and high temperatures.
As for the tool, we need:
Price of CBPB slabs different. It is determined by the plant and the direct supplier. But, if we consider the middle segment of the market, then for an 8-meter particle board, it is quite possible to pay from 700 rubles. per sheet. We already talked about sizes earlier. So, the average sheet area is almost 3.83 square meters.
If you compare this price with OSB sheets, then for a similar square footage we can pay more than 1000 rubles. Therefore, particle board is more profitable than other finishing materials.
Otherwise, decide on the thickness and remember that the larger it is, the more expensive the cost of one sheet will be. For example, a similar sheet, but with a thickness of 12 mm, can be found on sale at a cost of 1,100 rubles.
Advantages and disadvantages are important at the time of choice. They are worth considering, but you need to familiarize yourself with them first. Let's start with the advantages:
Today on sale there is not only gray DSP board, but also those that were originally finished as brick, ceramic tiles and other finishing options. All this allows you to inexpensively cladding your own house, bathhouse, garage and other buildings.
There are practically no disadvantages. Unless this includes big weight of CBPB board. This involves deepening the foundation, since the load on it will be large. During the installation process, it is necessary that the fasteners be galvanized or treated in a special way. Therefore, think about this moment in advance.
DSP board (cement particle board)- popular construction and finishing material, consisting of wood chips, Portland cement, water and special additives that provide the necessary performance characteristics.
The slabs are made by pressing. The result is durable sheets with smooth surfaces and ends, which allows you to significantly save time during their installation. This is a non-flammable material, so it is recommended for widespread use in construction.
DSP is used:

When performing construction and finishing works most important aspect is the reliability and durability of the resulting structure, but not all materials provide such parameters. That is why a cement bonded particle board with the necessary performance characteristics is an excellent solution. Products have their own characteristics that should be taken into account to achieve best result.
Explanation: CSP – cement particle board. The products include the following components:
The availability of the components of cement bonded particle boards determines their high popularity Products refer to composite materials and has been known for quite some time, which is confirmed by GOST 26816-86. For a long time it was unclaimed due to wide variety construction market.
At the moment, the production of the material is regulated by GOST 26816-2016. This standard is based on a 1986 document and European standards EN 634-1:1995 and EN 634-2:2007. Although the demand for products is increasing, due to their excellent qualities and reasonable prices, their availability remains quite low.
The plate manufacturing technology includes a number of successive stages:
Modern production is constantly developing, so it is possible to obtain CBPB sheets with minimum thickness 6 mm without loss of properties.
The material stands out from the rest with many advantages:
But the DSP board also has disadvantages:
When purchasing, pay attention to the presence of safety certificates.
The panels have a similar composition and allow you to choose suitable material For specific situation:
The characteristics of xylolite and fibrolite are very different, therefore their purposes are different
The use of new technologies allowed Arbolit to become a sales leader Also, parts are usually divided according to their area of use, depending on their thickness. There are two brands of products: TsSP-1 and TsSP-2, which differ in parameters.
Such facing material has the following properties:
